Katter delivers bizarre anti-SSM rant

Bob Katter has given a bizarre, rambling speech in Parliament on same-sex marriage that left fellow politicians scratching their heads and social media going in meltdown.

Mr Katter brought up everything from slavery, AIDS, "boys in dresses" Christianity, morality, Gianni Versace, "going bush is (SSM) became compulsory", while adding that he was absolutely not "anti-homosexual".

He also made wild accusations that gay people were "murderers" and "responsible for giving AIDS" to society through donating blood.

"You want to talk about equality? Well they wanted equality in the giving of blood. They said we have a right as homosexuals to give blood, so they did," Katter said.

"And I think it was 72 children were injected with AIDS from the blood that was given. It was hushed up. It was amazing to me that it never got any publicity at all."

Mr Katter said he wouldn't support marriage equality, accusing people who were homosexual of being more likely to commit crimes.

"There's no doubt there is a DNA thing and some people can handle it, but a lot of people don't, and there is a very ugly side to this," he said.

Mr Katter also said that people are "genetically programmed" to be heterosexual and that the LGBTQ movement had only appeared in the past 40 years.

He said he talked to some of his fellow Queenslanders, who had told him they were "going bush before they make [SSM] compulsory".

Mr Katter ranted about marriage equality "messing with heads" of young boys if you let them "go to school, wearing a dress".

He also said he "was not advocating that homosexual people should be put in jail", but blamed intolerance "on the opposition party".

Twitter user Josh Butler said: "Bob Katter has set the bar high for unhinged speeches in his career but he's doing himself proud in this marriage debate, having veered into criticisms of socialism, AIDS being spread by blood donations, and the 'vanishing race' of Australians."

Sydney Mardi Gras director Jesse Matheson said Mr Katter had made "the most foul speech I've ever heard. So bad".
